Banbitebq AC03P9 PID Replacement Control Board for Pit Boss Grills — Fits PB500SP/PB820SP/PB1150 (200–500°F, PID Precision)

Banbitebq AC03P9 PID replacement control board restores precise temperature control and advanced smoke settings for a wide range of Pit Boss pellet grills.

If your Pit Boss grill is showing erratic temperatures, unresponsive controls, or has a failed control module, this Banbitebq AC03P9 PID replacement board is engineered to bring stable, programmable heat back to your grill. Designed to match the original AC03P9 and PB1100PS1-A003 specifications, it fits multiple Pit Boss series models—Sportsman, Navigator, Mahogany, Pro and several PB-series grills—providing modern PID regulation, multiple cook modes and fuel-saving modulation.

How does this replacement board improve temperature accuracy?

The Banbitebq PID control board uses closed-loop PID algorithms to continuously adjust fan and auger outputs, holding the setpoint with tighter margins than simple on/off controllers. This minimizes temperature swings and keeps longer cooks consistent without repeated manual adjustments.

• Three dedicated PID profiles tuned for different cooking behaviors
• Continuous modulation of fan and auger for fine-grained control
• Temperature range from 200°F to 500°F for versatile use

Will it work with my specific Pit Boss model and how easy is installation?

This replacement is built to be compatible with AC03P9 and PB1100PS1-A003 and fits a broad list of Pit Boss grills including PB500SP, PB820SP, PB550G, PB1150G, PB440D2, PB700FB1, PB850G, PB820, and Pro 1100 models. Installation follows the same mounting points and connector layout as the original board, so many users can swap it in without specialized tools.

• Direct replacement for listed Pit Boss models and original part numbers
• Plug-and-play connectors that match factory wiring harnesses
• Typical installation requires basic hand tools and 20–40 minutes

What cooking modes and settings does the board provide?

The module supports nine temperature steps between 200°F and 500°F plus a special “P” setting that offers ten smoke-shift levels to prioritize smoke intensity. Together with eight cooking styles covered by the firmware, it adapts to smoking, searing and everything in between.

• 9 temperature settings for low-and-slow to high-heat searing
• "P" smoke setting with 10 incremental smoke shifts for flavor control
• Eight cooking profiles: smoke, bake, braise, roast, grill, barbecue, char-grill and sear

How does the board help save pellets and improve efficiency?

By dynamically altering auger and fan activity to match actual grill conditions, the control board reduces unnecessary pellet feed and keeps combustion more efficient. The result is steadier temperatures using less fuel over extended cooks.

• Advanced modulation reduces pellet consumption during stable phases
• Fan speed adjustments optimize combustion and heat retention
• Better temperature stability often shortens overall cook time and pellet use

Who this is for: Grill owners who need a direct, reliable replacement for a failing AC03P9/PB1100PS1-A003 control board and want improved temperature fidelity, expanded smoke control and better pellet efficiency. It's ideal for owners of compatible Pit Boss models who prefer a straightforward swap to restore factory-like performance and gain more consistent results on roasts, racks and long smokes.
